| Jan 25 at 21:42 | comment | added | Justme | @js1069 The difference between absolute and relative is simple. If you have a 1 meter stick, no matter if you throw it into ocean or take it on top of a mountain, the relative difference between stick ends is always 1 meter, even if one end of the stick is at - 11km or +8km in absolute relation of sea level. | |
| Jan 25 at 21:38 | comment | added | JVDS1069 | I'll definitely read into both of those more! Thank you guys so much. There are so many concepts I'm missing here lol. | |
| Jan 25 at 21:36 | comment | added | Justme | If it were a thing that the circuit depends on which load you put first in series with another load, then we could not use even two different resistors in series. | |
| Jan 25 at 21:36 | comment | added | JVDS1069 | I don't understand what "relative" and "absolute" voltage is. I definitely think I'm misunderstanding how electricity moves in a circuit. It's starting to seem like it doesn't "move" but somehow just exists and I don't understand in what way. I thought maybe the resistor would be in front of behind because of the way they are built, internally. But now I think the problem is just how I'm understanding the flow of electricity. | |

| Jan 25 at 21:15 | comment | added | winny | Look up KCL. Current is identical in both cases. | |
| Jan 25 at 21:15 | comment | added | user1937198 | Power is not a thing. Don't try and think about power as a thing that is traveling. Don't even think about voltage. Think about potential differences. Then current forms between the potential differences. And the power comes from the steepness of the difference and the amount of current. | |
